Not Dark Tower, but CBS turning Under the Dome into a 13 episode series.

From the article:

I hear the project’s writer Brian K. Vaughan (Lost) kept the general conceit and many of the characters from the book but also introduced new characters as regulars and tweaked some details and backstory for the existing ones.

Considering the unintelligible pile of crap that Lost eventually turned into, the fact that it’s head writer is leading this project is, IMO, a major red flag.
